/**
|
|
* YAML configuration loader. To use this class, construct it with path to
|
|
* a file and call its load() method. For specifying node paths in the
|
|
* various get*() methods, they support SK's path notation, allowing you to
|
|
* select child nodes by delimiting node names with periods.
|
|
*
|
|
* <p>
|
|
* For example, given the following configuration file:</p>
|
|
*
|
|
* <pre>members:
|
|
* - Hollie
|
|
* - Jason
|
|
* - Bobo
|
|
* - Aya
|
|
* - Tetsu
|
|
* worldguard:
|
|
* fire:
|
|
* spread: false
|
|
* blocks: [cloth, rock, glass]
|
|
* sturmeh:
|
|
* cool: false
|
|
* eats:
|
|
* babies: true</pre>
|
|
*
|
|
* <p>Calling code could access sturmeh's baby eating state by using
|
|
* <code>getBoolean("sturmeh.eats.babies", false)</code>. For lists, there are
|
|
* methods such as <code>getStringList</code> that will return a type safe list.
|
|
*
|
|
* <p>This class is currently incomplete. It is not yet possible to get a node.
|
|
* </p>
